Abstract

Elemental distributions of Fe, Mn, and Co in ultrathin FeMn/Co multilayers have been profiled by the x-ray anomalous scattering technique. Chemical intermixing is observed at the FeMn/Co interfaces with intermixing regions up to 14 Å. The chemical compositions in the intermixing regions are found to vary gradually from FeMn to FeMnCo₂ and from FeMnCo₂ to Co., respectively, but not from FeMn to Co. This result suggests that a reaction may occur and FeMnCo₂ appears at the interface during the deposition.
